Read the passage, then answer. In 1903, on the windy sands of Kitty Hawk, North Carolina, two brothers named Wilbur and Orville Wright test a flying machine. They run a small bicycle shop in Ohio, but they dream of human flight. At first, many people doubt them. The brothers study birds, read reports about gliders, and take careful notes. They build kites to learn how wings lift. Next, they make gliders and travel to Kitty Hawk because steady winds help testing. Each trip teaches them something new. One glider wobbles in the air, so they redesign the wings. Another model does not lift enough, so they adjust the shape. They also create a small wind tunnel to test wing designs. This tool helps them measure which shapes work best. In December 1903, they add an engine and propellers to a new machine. On December 17, they try again. Orville lies on the lower wing and grips the controls. The plane lifts, moves forward, and stays in the air for 12 seconds. It travels 120 feet before landing. Later that day, they fly three more times. The final flight lasts almost a minute. A strong gust then flips the plane and damages it. Even so, the brothers feel proud. They send a message to their family and begin planning improvements. Their careful testing, patience, and teamwork lead to a breakthrough. Soon, other inventors copy their ideas, and flying machines improve quickly. The Wright brothers show that big goals can be reached by small steps and steady learning.

Read the passage, then answer. In 1955, an African American woman named Rosa Parks lives in Montgomery, Alabama. She works as a seamstress and helps her community in quiet ways. On December 1, 1955, she rides a city bus home after a long day. The bus fills up, and the driver tells Rosa to give her seat to another rider. Rosa refuses and stays seated. She is arrested and taken to jail. Many people in Montgomery feel upset, but they also feel ready to act. Local leaders, including a young minister named Martin Luther King Jr., meet with neighbors and plan a bus boycott. Starting the next day, thousands of riders stop using the buses. Instead, they walk, share rides, and support each other. The boycott lasts for more than a year. It is not easy. People get tired, and some lose time at work. Still, they keep going because they want fair treatment. Finally, in 1956, the Supreme Court rules that bus segregation is unconstitutional. The city must change its rules. Rosa Parks’s quiet decision helps spark a larger movement. The passage shows how one brave choice can encourage many people to work together for change. Identify the best summary of the passage.

Read the passage, then answer. In 1947, a young student named Maya lives in New York City. She loves music, but she also enjoys science. One summer, she visits a library and finds a book about sound. The book explains that sound travels in waves. Maya wonders why some sounds are loud while others are soft. She decides to test the idea at home. First, she stretches different rubber bands around a small box. She plucks them one by one and listens closely. The tight rubber band makes a higher sound. The loose rubber band makes a lower sound. Next, she taps glasses filled with different amounts of water. The glass with more water makes a lower tone. Maya writes down what she hears and draws simple charts. Then she shares her results with her cousin Jamal, who plays the trumpet. Jamal explains that changing the length of the air path changes the note. Maya realizes that many instruments use the same basic rule. That fall, she creates a small display for the school science fair. She labels it “Sound Changes with Vibration.” Her teacher praises her clear notes and careful steps. Maya does not invent a new instrument, but she learns how scientists think. She asks questions, tests ideas, and uses evidence. The project also helps her appreciate music in a new way. She hears each note as a pattern of vibrations.

Read the passage, then answer. In 1911, a scientist named Marie Curie works in Paris, France. She has already helped discover new substances called radium and polonium. Her work is difficult and tiring. She and her team stir heavy pots of crushed rock for hours. They do this to separate tiny amounts of useful material. Marie keeps careful records and repeats tests to confirm results. Some people doubt her because she is a woman in a field led mostly by men. Still, she continues because she believes evidence matters most. In 1911, she wins the Nobel Prize in Chemistry for her discoveries and for isolating pure radium. She becomes the first person to win Nobel Prizes in two different sciences. Marie also uses her knowledge to help others. During World War I, she supports mobile X-ray units so doctors can see injuries inside the body. She trains workers and travels to hospitals. Her efforts save time and improve care. The passage shows Marie Curie as a determined scientist who combines curiosity with service. Her story teaches that persistence and careful work can lead to important progress.

Read the passage, then answer. Chen joins his school’s gardening club in early spring. He likes being outdoors, but he has never grown food. The club leader, Ms. Rivera, explains that plants need sunlight, water, and healthy soil. She also says that gardens take patience. Chen and his friends plan the beds and choose seeds. They plant lettuce, beans, and carrots. At first, Chen waters too much because he worries the seeds will dry out. A few days later, the soil looks muddy, and some seeds do not sprout. Ms. Rivera shows Chen how to check the soil with his finger. If it feels damp an inch down, the plants can wait. Chen changes his routine and waters less often. Soon, small green leaves appear. Chen feels proud, but new problems come. Tiny holes show up on the lettuce leaves. The club finds caterpillars hiding under the plants. Instead of using harsh sprays, they gently pick off the caterpillars and cover the beds with light cloth. The plants recover and keep growing. By early summer, the garden is full of color. The club harvests vegetables and donates some to a local pantry. Chen learns that mistakes can become lessons. With guidance and teamwork, he becomes a careful, confident gardener.

Read the passage, then answer. In 1969, the United States plans a mission called Apollo 11. The goal is to land people on the Moon and return them safely. Three astronauts train for months: Neil Armstrong, Buzz Aldrin, and Michael Collins. They practice in simulators that copy the spacecraft’s controls. They also learn how to handle emergencies. On July 16, 1969, the rocket launches from Kennedy Space Center in Florida. It rises with a loud roar and disappears into the clouds. After traveling through space, the crew reaches the Moon. Collins stays in orbit in the command module. Armstrong and Aldrin move into the lunar module, named Eagle, and begin their descent. The landing is tense because the computer gives alarms. Armstrong takes manual control and finds a safer spot. On July 20, Eagle lands. Later, Armstrong steps onto the Moon’s surface and speaks a famous line. Aldrin follows and describes the view as beautiful and quiet. They collect rocks and set up experiments. After a few hours, they lift off and reunite with Collins. The crew returns to Earth on July 24 and splashes down in the ocean. People around the world celebrate. The mission proves that careful planning and teamwork can achieve a difficult goal.

Read the passage, then answer. In 1930, a scientist named Clyde Tombaugh works at an observatory in Arizona. He is young and does not have a college degree, but he is skilled at observing the sky. Astronomers suspect there may be a ninth planet far beyond Neptune. They call it “Planet X.” Clyde is given a careful task. He takes photographs of the same area of the sky on different nights. Then he uses a device called a blink comparator. It lets him switch quickly between two images. Most stars stay in the same place, but a planet should shift slightly. Night after night, Clyde checks tiny dots. The work requires patience and sharp focus. On February 18, 1930, he notices a small object that moves. He reports it, and other astronomers confirm the finding. The new object is later named Pluto. At first, people call it a planet, and it becomes famous in textbooks. Many years later, scientists learn more about Pluto and similar objects. Pluto is reclassified as a dwarf planet, but its discovery remains important. Clyde’s story shows how careful methods can lead to new knowledge. It also shows that science can change when new evidence appears. Which of the following best summarizes the passage?

Read the passage, then answer. In 1990, the Hubble Space Telescope is launched into orbit around Earth. Scientists hope it will take sharp pictures of stars and galaxies. Soon after launch, a problem appears. The main mirror is slightly the wrong shape, so images look blurry. Many people feel disappointed, and some question the project. Engineers and astronauts, however, do not give up. They study the problem and design special tools to correct it. In 1993, astronauts travel to Hubble on a space shuttle. During several spacewalks, they install new parts that act like glasses for the telescope. The work is slow and careful. Astronauts must use thick gloves and follow exact steps. When Hubble turns back toward space, the new images are clear. Scientists can now see distant galaxies, glowing clouds of gas, and newborn stars. Hubble’s pictures help people understand that the universe is vast and changing. The telescope also collects data that supports new ideas about how fast the universe expands. Over time, Hubble becomes a symbol of fixing mistakes with teamwork and planning. The passage shows that a setback does not have to be the end. Which of the following best summarizes the passage?

Read the passage, then answer. In 1876, Alexander Graham Bell works on ways to send sound over wires. He wants people to speak to each other from far away. Bell and his assistant, Thomas Watson, spend many days testing parts. Sometimes the wires crackle, and sometimes nothing happens at all. Bell keeps a notebook of ideas and sketches. He learns that a thin membrane can vibrate like an eardrum. If the vibration changes an electric current, it might carry sound. On March 10, 1876, Bell tries a new setup in his Boston lab. He accidentally spills liquid on his clothes and calls out, “Mr. Watson, come here, I want to see you.” Watson hears the words through the device in another room. The message is simple, but it works. The invention becomes known as the telephone. Soon, Bell demonstrates it to others, and interest grows. Over time, telephones connect homes, businesses, and cities. The passage highlights the value of experiments and teamwork. It shows how a practical need can inspire a new invention. Identify the best summary of the passage.
